VAULT DOOR Filed Sept. 30, 1950 5 Sheets-Sheet 5 IN V EN TORS John P. Paca Qv BYJazn H. Elz er @me WM A TTORNEYS Unite States Patent O VAULT DOOR John P. Paca and John H. Ebner, Canton, Ohio, assignors te; Diebold, Incorporated, Canton, Ohio, a corporation o Ohio s Application September 30, 1950, Serial No. 187,756 11 Claims. (Cl. 109-59) The invention or discovery relates to vault doors used as parts of vault structures in banks, government oices, and'other places of business where it is desired to store and safeguard valuables such as money, documents, and other articles.

In such a vault construction, access is had to the interior of the vault through a vestibule at the outer end of which is located a door frame. The door for the vault is hinge mounted at one side on a jamb of the door frame.

Such a usual vault door may be circular, but the present invention or discovery relates to rectangular vault doors and the rectangular door frames therefor.

The usual rectangular vault door prior to the present improvements has bolt work operatively mounted on its inside rectangular face, and one or more bolt locking units are mounted on the inside rectangular face of the door and adapted to be operated to selectively maintain the bolts of the bolt work in extended engaging position with stops on jam members of the door frame when the door is closed, and it is desired to prevent its being opened by an unauthorized person or persons.

The locking units are usually one or more combination locks each having a dial on the outside rectangular face of the door, and each having a combination setting spindle which extends through the door from the lock on the inside rectangular face and terminates on the outside of the door in a knob having a pointer which is utilized in connection with the dial for setting the combination in a well known manner.

The locking units may also include a time lock, and when the locking units are unlocked, the bolts of the bolt work may be extended and withdrawn by an operating handle extending from the outside rectangular face of the door.

In the manufacture of such a usual rectangular vault door having bolt work and bolt locking units mounted on the door itself, considerable difficulties are encountered because such bolt work includes a plurality of bolts and common operating mechanism, all of which must be properly located and fitted on the door, and associated with the bolt locking units.

Moreover, in the installation of such a usual vault door having bolt work and bolt locking units mounted directly thereon, considerable ditiiculties are encountered in effecting the proper adjustments of the working parts.

The relatively large number of parts in usual bolt work and bolt locking units mounted directly on a vault door and the diiculties encountered in the manufacture and installation of the same necessitate a relatively high cost to the purchaser of the vault door.

The objects of the present invention or discovery include the provision of an improved andV simplied vault door construction including a vault door, a door frame hinge mounting the door, and associated bolt mechanism and bolt locking units, the improved vault door construction having parts which are substantially reduced in number as compared with usual vault door construction including usual bolt work, and the parts having a construction and arrangement which eliminate many of the manufacturing and installation diiiiculties encountered in connection with usual rectangular vault doors having usual ice bolt work and bolt locking units directly mounted thereon.

Further objects of the present invention or discovery include the provision of suchv an improved vault door construction, and in which the construction and arrange ment of parts give the door and frame a clean and smooth appearance both when viewed from the outside or from the inside of the vault.

The foregoing and other objects are attained by the vault door construction, parts, combinations, and subcombinations, which comprise the present invention or discovery, the nature of which is set forth in the following general statement, and preferred embodiments of which, together with their mode of use, are set forth by way of example in the following description, and which are particularly and distinctly pointed out and set forth in the appended claims forming part hereof.

The improved vault door construction is indicated generally by 10, and includes walls forming a rectangular vestibule indicated generally by 11 and having at its front end, members forming a rectangular door frame indicated generally by 12. A vault door indicated generally by 13 is mounted at one side by hinges 14 on one of the side members 15 of the door frame.

The door frame 12 engirdles a rectangular opening, and the door 13 ts in the opening when closed, as shown in full lines in the several views of the drawings. The open position of the door is shown in dot-dash lines in Fig. 3.

The improved vault door construction 10 is adapted for being incorporated in a vault which may be of any usual vault construction, and has a front wall 16 indicated conventionally in Figs. 3 and 4, and a floor 17 indicated conventionally in Fig. 4.

In the drawings, the vestibule 11 including the door frame 12 is shown, for purposes of convenience, as if made of a one-piece casting. It is noted, however, that the vestibule 11 and the door frame 12 may be made,

and. usually are made of composite plate and bar construcy tion, in which the members are welded, bolted, screwed, or otherwise connected with each other. In the present improved Vault door construction 10, the improvements are constituted in part by the external conformations of the vestibule 11, the door frame 12, and the door 13, and the manner in which these parts are built is a matter of design.

The door 13 includes a main rectangular body 18, which in the drawings, for purposes of convenience, is similarly shown as if made in one piece, since the detail construction of the rectangular body 18, excepting for its external conformation, is not a part of the present improvements. In practice it is usual that the main door body 18 be of composite construction, which varies according to the engineering specifications for the door.

The front vault wall 16 has formed therein a rectangular opening indicated by 19, and the vestibule 11 when installed is located in the vault wall opening 19 as shown in Figs. 3 and 4. The door frame 12 at the front end of the vestibule 11 includes the laterally extending flange member 15 at one side, a similar laterally extending flange member 20 at the other side, and a laterally extending ange member 21 at the top.

In the installation of the vault door construction 10, a foundation plate 31 is positioned upon the floor semi-finished top face 30 at the bottom of the Wall opening 19, and the vestibule 11 is positioned in the wall opening 19. The vestibule 11 includes bottom members indicated generally by 32 which have flat bottom faces seating upon the at top face of the foundation plate 31. The nish portion 33 of the oor 17 is then applied upon the semi-finished face 3i), and the iinish oor portion 33 has a floor line 34 in the banking room, and a iloor line 35 inside the vault at a slightly higher elevation than the oor line 34.

The door frame 12 includes a side jamb member 36 at the hinge side of the frame, a side jamb member 37 at the lock side of the frame, a top jamb member 38, and a bottom jamb member 39. Each of the jamb members 36, 37, and 38 has a bevelled jamb face 40 which slopes from front to rear so that the opening in the door frame is smaller at the rear than at the front. The bevelled jamb faces 40 of the door frame 12 mate with similar bevelled jamb faces 41 on the sides and top of the door 13 when the door is closed. The upper face 42 of the bottom jamb member 39 is horizontal as shown, and the bottom jamb member 39 has a stop flange 43 projecting upwardly above the face 42. Similarly, the top jamb member 38 has a stop ange 44 projecting downwardly from the face 40.

The hinge side jamb member 36 has a rear face 45 meeting its bevelled jamb face 40 at a rear upright corner 46. A tongue bar 47 preferably extending the entire length of the hinge side jamb member 36 is secured to the jamb member 36 in abutment with its rear face 45. The tongue bar 47 includes an outer bevelled tongue portion 48 extending laterally beyond the jamb face 40 and over thecorner 46.V

The main door body 18 as shown has a longitudinally extending rabbet 49 formed in its hinge side rear corner, and the rabbet 49 has a flat bottom face 50 which lies in a common plane with the rear face 45 of the jamb member 36 when the door 13 is closed, as shown in Fig. 3. A grooveforming bar 51, preferably extending the entire length of the door, is secured in the rabbet 49 and in abutment with the rabbet bottom face 50. The groove forming bar 51 includes a longitudinally extending bevelled flange portion 52 transversely spaced from and extending laterally over the outer border portion of the rabbet bottom face 50 and forming therewith a transversely bevelled groove 53 in which the tongue portion 48 of the tongue bar 47 fits when the door is closed.

The lock side jamb member 37 has a rear face 54 meet ing its bevelled jamb face 40 at a rear upright corner 55. The main door body 18 has a longitudinally extending rabbet 56 formed in its lock side rear corner, and the rabbet 56 has a ilat bottom face 57 which lies in a common plane with the rear face 54 of the jamb member 37 when the door 13 is closed, as shown in Fig. 3. A groove forming flange bar 58, preferably extending the entire length of the door is secured in the rabbet 56 and in abutment with the rabbet bottom face 57. The groove forming bar 58 includes a longitudinally extending bevelled flange portion 59 transversely spaced from and extending laterally over the outer border portion of the rabbet bottom face 57 and forming therewith a transversely bevelled groove 60. The rabbet bottom face 57 of the door 13 meets with the bevelled face 41 at a corner 61 which is aligned with the corner 55 of the jamb member 37, when the door is closed. The flange portion 59 of the groove forming bar 58 has a longitudinally extending side Vface 62 which is ofset as shown from the corner 61 in the direction of the hinge side of the door 13.

The construction and combination of the door body 18 and the groove forming bars 51 and 58 may be broadly defined as constituting a door having in each of its side faces, and preferably at each of its rear corners a laterally opening transversely bevelled longitudinally extending groove. The construction and combination of the hinge side jamb member 36 and the tongue bar 47 may be broadly defined as constituting a jamb member having a bevelled jamb faoe and a tongue extending beyondpthe bevelled jamb face and fitting in the hinge side longitudinally extending groove of the door when the door is closed. f

On the rear face 54 of the lock side jamb member 37 there is located a tongue bolt bar 63, which preferably extends the entire length of the lock side jamb member 37 and is operatively mounted for lateral movement crosswise of the corner 55 and the rabbet face 57 of the door body 18 when the door is closed. The tongue bolt bar 63 includes an outer bevelled tongue portion 64 which as shown at all times extends laterally beyond the jamb face 40 and the corner 55. When the door is closed Yand the bolt bar is laterally extended for bolting the door,

the tongue portion 64 of the bolt bar 63 extends into the groove 60 as shown in Figs. 3 and 8. When the bolt bar 63 is retracted as shown in Fig. 10, the tongue portion 64 is withdrawn laterally out of the groove 60 and clears the side face 62 of the tongue portion 59 of the groove forming bar 58, thereby permitting opening of the door.

The operative mounting of the bolt bar 63 for lateral movement on the lock side jamb member 37 may be effected by a number of different means. Preferred means for operatively mounting the bolt bar 63 on the lock side jamb member 37 for lateral movement with respect to the jamb member are illustrated and described in detail hereinafter. When the bolt bar is extended in the position bolting the door as shown in Figs. 3 and 48, itis necessary that one or more lock units be associated 6 with the bolt bar and its mounting means or mechanism for locking or stopping the bolt bar in its extended door bolting position. Preferred multiple lock units, associated with the bolt bar and its mounting means, are illustrated and described hereinafter.

The bolt bar 63 has a longitudinally extending rabbet 65 formed in its inside corner adjacent the rear face S4 of the lock side jamb member 37 as best shown in Figs. 3, 8, and 10.

Each lever plate 98 has an arm 108 extending from its pivot pin 93 away from the bolt bar 63. The lever plate 103 likewise has an arm 109 extending away from the bolt bar 63. A connecting link bar 110 extends longitudinally of the jamb member 37 beneath the arms 108 and 109 of the lever plates 98 and 103. A pivot pin con- Ynection 111 is provided between the connecting link bar 110 and each arm 108 of the lever plates 98, and a pivot 8 connection 112 is provided between the arm 109 of the leverplate 103 and the connecting link bar 110.

In Fig. 5 the bolt bar 63 and the parts of the linkage means 92 are shown in their relative positions when the bolt bar is extended to its door bolting position. When either of the operating handles or 97 are turned counterclockwise as viewed in Fig. 6, the bolt bar 63 is reciprocated out of the groove 60 as shown in Fig. l0, permitting opening of the door 13.

Means controlled by a plurality of lock units are provided in the vault door construction 10 for locking the bolt bar 63 in its extended door bolting position. In the vault door construction 10, the lock units are mounted on the rear face of the cover plate 70 and have operative connections with parts associated with the bolt bar 63, so that the bolt bar 63 cannot be withdrawn from its extended door bolting position when any of the lock units are set in the locking arrangement of its parts.

As shown, thelock units include a lower combination lock 113, an upper combination lock 114, and a time lock 115 above the upper combination lock 114. The combination locks 113 and 114 are of usual construction, and each includes a bolt 116 which is extended to the positions shown in Fig. 7 when the door 13 is bolted and the combination locks 113 and 114 are lock set. These bolts 116 are withdrawn to the positions shown in Fig. 9 when the combination locks 113 and 114 have been manipulated so as to permit the withdrawal of the bolts 116. The manipulation of each combination lock is etected by means of a spindle 117 which extends through the cover plate 70 and the jamb member 37, and has on its outer end a knob 11S cooperating with a dial plate 119.

The time lock 115 is of usual construction, and includes a plunger 120 which is extended as shown in Fig. 7 when in the locking position and which is withdrawn as shown in Fig. 9 when in the unlocking position. A release arm 121 is operative from inside'the vault for withdrawing the time lock plunger 120.

A slide block 124 reciprocably tits in the channel 123 and is connected with the outer extremity of the time lock plunger 120. A pivot stud 125 is located above the slide bearing 122 and extends rearwardly from the rear face of the cover plate 70. A lever 126 is pivoted on the pivot stud 125 and includes a lower arm 127 having a slot and pin connection 123 with the slide block 124.

The lever 126 includes an upper arm 129, and the cover plate 70 has a horizontal slot 130 formed therein beneath the outer extremity of the lever arm 129. Beneath the cover plate 70 there is mounted on the guide plate 87 an L-shaped extension bar 131 having an outer base leg 132 on which is mounted a pin 133 which extends through the cover plate slot 130. At the extremity of the upper arm 129 of the lever 126 there is formed a slot 134, and the outer end of the pin 133 extends into the slot 134.

Thus, when the time lock 115 is in the locked arrangement of its parts as shown in Fig. 7, its plunger 120 is extended and maintains the slide block 124 in a position tothe right of the pivot stud 125, whereby through the connections of the lever 126 with the slide block 124 and the extension bar 131, the bolt bar 63 is maintained in its door bolting position independently of the locking action of the combination locks 113 and 114.

Referring to Figs. 5 and 6, the guide plate 81 has formed therein a central notch 135, and on the rear face of the guide plate 81 there is secured a check or stop plate 136 having formed therein a notch 137, the notches 135 and 137 opening away from the bolt bar 63. Between the guide plate 81 and the link bar 110 there is mounted on the rear face 54 of the jamb member 37 a guide block 13S horizontally opposite the notches 137 and 135. The guide block 138 has formed therein a rearwardly opening vertically extending guide channel- 139. A lock blockv 140 tits and vertically reciprocatesl in the channel 139, and a pin 141 extends rearwardly' from the lock block 140. When the lock block 140 is in its lower position as best shown in Fig. 5, it is in locking abutment with the lower portion 142 of the check or stop plate 136 preventing withdrawal of the bolt bar 63 from its door bolting position. When the lock block 140 is elevated to the position best shown in Fig. 6, it is aligned with the notches 137 and 135 and permits the withdrawal of the bolt bar 63 to the position best shown in Fig. 6 in which the bolt bar 63 is disengaged from the groove 6i), permitting opening of the door.

Through a link and lever connection between the bolts 116 of the combination locks 113 and 114 and the pin 141, the lock block 140 is maintained in its lower door bolting position as best shown in Fig. 7 when the combination locks 113 and 114 are set in the locking arrangement of their parts with the bolts 116 extended.

When the combination locks 113 and 114 are manipulated to the unlocked arrangement of their parts, and the bolts 116 are withdrawn as best shown in Fig. 9, the lock block 140 is elevated to its position shown in Fig. 6, and the bolt bar 63 may be withdrawn out of bolting engagement with the groove 60.

Between the combination locks 113 and 114 the cover plate 70 has formed therein a vertically extending slot 143, and the pin 1'41 extends from the lock block 140 through the slot 143 and rearwardly of its rear face.

The link and lever-means connecting the bolts 116 of the combination locks 113 and 114 includes a lock link 144 which has a pivotal connection 145 of its lower end with the outer end of the bolt 116 of the lower combination lock 113. The upper end of the lock link 144 has a pivotal connection 146 with the outer end of the bolt 116 of the upper combination lock 114. The lock link 144 has formed therein a slot 147 which is inclined from its lower end away from the vertical, the pivotal connections 145 and 146 being vertically aligned with each other when the bolts 116 are extended asy shown in Fig. 7. Beneath the lock link 144 is located a lock lever 148 which is pivotally mounted on the rear face of the cover plate 70 by a pivot screw 149 which is located above the slott 147. A screw pin 150 extends through the slot 147 and is screwed in the lock lever 148, the slot 147 and pin constituting a slot and pin or loose connection between the lock link 144 and lock lever 148.

The lock lever 148 has formed therein an upwardly opening notch 151 shown in full lines in Fig. 7, and the outer extremity of the pin 141 is seated in the bottom of the notch 151. A latch hook 152 has a lower end having a pivotal connection 153 with the lock lever 148 adjacent its lower face. The latch hook has an upper hook end 154, and the latch hook is spring pressed so that its hook end 154 is ordinarily hooked over the outer extremity of the pin 141.

When the door is bolted as shown in Figs. 3, 5, and 7, and the combination locks are set with their parts in the locking positions, and it is desired to unlock and unbolt the door', it is first necessary that the time lock 115 shall have been operated to release its plunger and permit movement of the slide block 124. It is then necessary that the knobs 118 of the combination locks 113 and 114 be manipulated to set the tumblers of the combination locks in positions permitting withdrawal of the bolts 116. The bolts 116 are then withdrawn by the usual operation of the knobs 118 from the positions shown in Fig. 7 to the positions shown in Fig. 9, thereby through the link and lever connecting means between the bolts 116 and the pin 141 elevating the lock block 140 to the position shown in Fig. 6 is which it is aligned with the notches 135 and 137 of the guide plate 81 and the check or stop plate 136. The outer handle 95 may then be rotated to turn the shaft 94 counterclockwise as viewed in Fi'g. 6, whereby the turning of the lever plate 103 with the shaft 94, and through the link connection of the lever plte 103 with' the bolt `11') bar 63' and through the connection of the lever plate 103 by the link bar 11G-with the lever plates 98 andv their link connections with the bolt bar 63, will effect withdrawal of the bolt bar 63 to the door releasing position shown in Figs. 6, 9, and l0.

lf by accident a person is locked in the vault, when the door 13 is bolted and the lock units are set in the locking positions of their parts, the person solocked in the vault may unlock the lock units 113 and 114 enabling the bolt bar 63 to be withdrawn by turning-the inside handle 97.

For this purpose the person in the vault manipulates the time lock release arm 121, permitting movement of the plunger and connected parts from their locking position shown in Fig. 7 to the unlocked position shown in Fig. 9.

The latch hook 152 is then swung so that its hook end 154 is disengaged from above the outer extremity of the pin 141, and the pin 141 is then manually lifted so as to move the lock block to the unlocked position shown in Fig. 6, where it is held while the handle 97 is being turned to withdraw the bolt bar 63 from engagement with the door 13, and permitting opening of the door.

The door 13 is provided on its outside with a handle 155 for pulling the door open or pushing it closed from the outside. From the inside the door is pushed for opening it.

As shown, and preferably, architrave and pilaster trim members indicated generally by 156 are mounted on theoutside of the side and top members of the door frame 12.
